Be it known that we, CARL HENRIK SCHA- GER, residing at Stockholm, and J OHANNES MAGNUS J ONASSON LUNDIN, residing at War- 5 tan, Sweden, subjects of the King of Sweden and Norway, have invented a new and useful Improvement in Looks for Railway-Switches, (for which we have obtained patents in Sweden, Nos. 6,9'71 and 7,196, datedApri129, 1895;

in Finland, No. 648, dated October 3, 1896; in

apparatus for operating and locking of railway-switches to the best advantage.

The object of the invention is to provide simple and reliable apparatus for operating 2 5 and locking railway-switches, so as to obtain the advantages of the switch being rigidly locked when the signal shows clear for trains or cars coming from the outside toward the switch, while at the same time the construction is such that when the switch is not locked it may be easily opened by a'train or car coming out von the track for which the switch is not laid without damaging the track or switch or getting derailed. The construction is also such that theswitch may beequally Well be operated at the place or at a distance, so that switching may be done out on the train-yard when no train is expected to come through the switch from outside; 40 but the apparatus may be locked from a distance-for instance, the railway-station-to prevent its being manipulated when a train to the station.

the switches when it is allowed without going The invention consists in the combination and arrangement of parts as hereinafter set forth. Y

In the drawings, Figure 1 is a plan view of the apparatus applied to a switch on a rail- Way-track. Fig. 2 is an elevation endwise of the apparatus, and Fig. 3 is a partial side clevation. Figs. 4 to 8 are detail views of the lever mechanism.

Similar letters of reference indicate correa friction-roller and running in a slot 0 in a This invention relates to improvements in cam-plate e, which in its turn runs in suitable guides cl in adirection at right angles to the length of the rod a. Said cam-plate is pref- 7-0 erably placed abovethe rod (t, but may also be placed below the same, and the slot 0 runs obliquely against the direction of the length of the rod, so that by moving the cam-plate in the same direction as a track runs the rod a will, bymeans of said slot and tap, be forced to move inthe direction of its length, whereby the switch will be operated, For moving the said cam-plate c a lever f is pivoted in a suitable chair fixed to the cross-ties and by means of a pulley f and rod f connected to the said cam-plate, so that by moving the lever f over to one side or the other the switch may be operated at the spot. The said lever f is also, by means of ropes e and pulley f, connected to another lever m, placed at a distance-for instance, at the depot-so that the switch may be also operated by means of the last-mentioned lever. The said rod a extends farther toward a vertical axle or shaft, which 0 is held by suitable bearings in a post and may either on its top carry a signal-disk or by means of wire ropes j be so connected to another similar rod g, carrying a signal-disk, that they are both turned at the same time. At the bottom the said rod g is provided with a cam or hook h, which is so placed or arranged that when the signal shows clear it runs in either of two slots Ki in the end of said cross-bar a. Said slots are placed so that when the cam or hook h runs in one of them the points of the switch-rails are laid and locked for one track, and when the hook runs in the other the switch is locked for the other track. The signal is by means of ropes I j connected with a lever for operating the -actly as shown in the drawings.

same, which lever is placed beside the lever m for operating switch at a distance. The result of this arrangement is that the stationmaster at the depot may himself see that the switch is laid for the right track and thereafter lock the same by placing the signal to show clear, whereupon the yardmen are unable to interfere with the switch or do any switching until the station-master (after the train has passed the station) unlocks the switch bymoving the signal to show stop. The last-mentioned position of the signal-disk is shown in the drawings by dotted lines.

The before-mentioned lever m for operating the signal at the station is on one side provided with a shield 19, Figs. 7 and 8, so fixed and placed that it displays different sides for the two different positions of the lever and switch. The side corresponding to the switch being laid for the main track may be painted or otherwise marked, for instance, 1, and the other side similarly painted or marked 2, so that by looking at the shield the station-master may ascertain for which track the switch is laid.

The before-mentioned lever for operating the signal is on one side provided with a shield O, protruding over the post n, in which the lever 70 is pivoted. Saidshield is bent to a curve of the same radius as the circle in which it moves when the lever is operated, and the top of the post nis suitably painted or marked F Stop on the part covered by the shield when the signal stands for stop and similarly marked Clear on the part covered by the shield when the signal stands for clear. The station-master is thereby enabled to ascertain the position of the signal without being obliged to directly look at the same.

The invention need not be carried out ex- So, for instance, may the tap b and cam-plate 0 change places, as will be well understood by any person skilled in the art to which it appertains The operation of the apparatus is obvious.

When a train is expected, the switch is laid for the right track by means of either levers m or f and the signal set to show clear and the switch locked by means of the lever is. Before the train arrives the station-master may by looking at the levers m and is himself ascertain Whether the switch is laid for the right track or not and whether the same is properly locked and signal rightly set or not. After the train has passed the signal is placed to show stop, whereby the switch is unlocked, so that the same may be shifted at the spot by means of the lever f or at the station by means of the lever m.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In apparatus for operating and locking of railway-switches the combination of a crossbar connected to the switch-points, a camplate adapted to move the said cross-bar, a switch-lever connected to the said cam-plate, a second switch-lever connected to the firstmentioned switchlever, a cam or hook connected to a signal and adapted to hold the said cross-bar in either of its extreme positions, when the signal shows clear, and a lever for operating said signal, substantially as and for the purpose set forth.

2. In apparatus for operating and locking of railway-switches the combination of a crossbar movable in the direction of its length and adapted 'to move the switch-points, a camplate movable in the direction of the rails and adapted to move the said cross-bar, a switchlever adapted to move the said cam-plate, a second switch-lever provided with signs showing the position of the switch and by means of suitable transmissions, such as wire rope, connected to the first-mentioned lever, a cam or hook connected to a signal-disk and catching in suitable notches in the said cross-bar so as to hold the switch-point in either of its extreme positions, and a lever provided with signs showing the position of said signal-disk and connected so as to operate the same, as and for the purpose set forth.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 30th day of December, 1896.
